Digital visualization: The application of digital visualization large screens in bridge management is also becoming increasingly important. This kind of large screen can help bridge managers better monitor the status and health of the bridge, and display the traffic situation of the bridge in real time, including the flow and speed of vehicles and pedestrians. Through these data, the manager can find the problems existing in the bridge in time, and take corresponding measures for repair and maintenance, so as to avoid more serious damage. In addition, the digital visualization screen can also help predict the future use of the bridge, provide data support for future planning and decision-making, and improve the efficiency and safety of the bridge
